Per Deadline, Searchlight Pictures has nabbed Saoirse Ronan, Sam Rockwell, and David Oyelowo for Tom Georges untitled murder mystery project. Deadline explains the synopsis as follows:
The story is set in 1950s London, where a desperate Hollywood film producer sets out to turn a popular West End play into a film. When members of the production are murdered, world-weary Inspector Stoppard (Rockwell) and overzealous rookie Constable Stalker (Ronan) find themselves in the midst of a puzzling whodunit within London’s glamorous Theatreland and sordid underground.
